The interior of Ilvarael was everything the outside had promised and more.
The moment the heroes stepped through the archway carved into the trunk, the living wood settled around them — not confining, just present, the way old forests feel present. The hallways were wide and high-ceilinged, shaped from heartwood that held its own steady amber warmth, every surface breathing with a kind of life that stone and plaster never could. Leaves pushed through crevices in the walls. Roots crossed overhead, entwined into arches. The floors were smooth and faintly warm underfoot — the tree's own heartbeat, slow and constant, felt through the soles of their boots.
Professor Faelwen led them forward as the Emperor and Empress moved ahead to attend to their obligations. She walked at an unhurried pace, and after a moment, began to speak — not loudly, but with the particular rhythm of someone who has been choosing her moment carefully and has decided this is it.
"I know you must all feel the distance from home right now. The cultural difference, the language barrier — all of it at once." She glanced back at them. "But there's no need to be on edge. You are honored guests here. That is not a formality — it is how you will be treated."
A pair of elven servants passed without sound, inclining their heads as they went — not subserviently, but with the measured courtesy of people who considered composure a form of respect.
"You won't only be training your strength here," Faelwen continued. "You'll be growing in spirit and in mind as well. Deepening your knowledge of a culture entirely unlike your own." She paused briefly. "And to make that possible — given how seriously we elves take our customs when it comes to those from other worlds — you must first learn the most fundamental gateway into our hearts."
"That being language. Not translation — language. The elves have always held that you cannot truly know a people until you know how they speak. The shape of a language tells you how a people think. What they value. What they've lost. What they protect." Another glance back, deliberate this time. "Which is why the first thing asked of you — as guests and as heroes — will be to learn Elarith."
"Your language?" Misaki said.
"Your language too, for the duration of your time here. The Emperor speaks English — as do several of the court nobility, as an extension of their respect and their own elven pride. But they will not always translate for you. The expectation is that you meet them partway." She met each of their eyes in turn. "Beginning today."
She let that land for a moment, then added: "Besides — a hero who cannot speak with the people they're meant to protect and serve is only half a hero, isn't that right?"
The words settled over the group with a quiet weight. No one argued.
It was Jupiter who broke the silence, raising his hand slightly. "In that case — what did Lady Feyre mean earlier when she called us by that word? I could barely pronounce it. Thaelar. That one. What does it mean?"
"I'd like to know too," Xavier said immediately. The others nodded in agreement.
Faelwen's expression shifted — a small, satisfied smile, the particular one she wore whenever she was about to teach something she genuinely loved. She adjusted her glasses and stood a little straighter.
"Thaelar is the plural form of Thael — which means Hero in Elarith. You will hear it often from here on, directed at all of you, so it's worth keeping close to mind."
She held up one finger before they could respond, as though she'd just remembered something she'd nearly forgotten. "And one more thing — whenever you meet an elf, greet them with the word Vaela. It's the standard respectful greeting in our language, equivalent to 'Good morning' in spirit, though it carries more weight than that in practice." Her tone shifted slightly — still warm, but firmer. "This is not optional. Elves take perceived disrespect very personally, even when it comes from ignorance. Using Vaela costs you nothing and buys you a great deal of goodwill. It will save you from headaches you don't want, and from lectures you certainly don't need."
A beat.
"Trust me on that one."
As her words settled, something shifted in the air around the group — something quiet and collective. The understanding, arriving fully for perhaps the first time, that they were no longer in the human realm. Not just in a different country. Not just in unfamiliar territory. They were in another world entirely, governed by its own rhythms and norms and expectations, none of which overlapped with what they'd grown up knowing. The weight of that was enormous and real and somehow, standing in the warm glow of a living hallway in a tree that had been growing since before any human kingdom existed — entirely, unexpectedly exciting.

Their quarters were on the thirty-first level, reached by a spiraling pathway that wound upward through the interior of the tree. Through the open sections of the inner wall, the full scale of Ilvarael's interior became visible — a vast open shaft of living wood going up and down further than the eye could track, lit walkways and bridges at every level, living branches crossing through the open air to anchor themselves in the far wall, the whole structure breathing and glowing and alive in a way that made the human concept of "building" feel like a very small idea.
Jason walked with his head tilted back for most of the climb, which meant he walked into a low-hanging root twice. No one acknowledged this. He seemed to consider it a fair trade.
The rooms themselves were beyond generous — the royal family had ensured the heroes received nothing less than the highest standard the palace could offer, a fact that was apparent from the first step through each door. Every chamber had been shaped from living heartwood, furnished with materials grown rather than crafted, the surfaces worn smooth over centuries of use. Deep window seats looked out over the canopy, where the triple moons were now fully risen and the bioluminescent leaves caught their light and gave it back in slow pulses. Folded clothes waited on a shelf of woven material — elven-cut, simpler than anything the heroes had been wearing, in colors drawn from the forest: deep green, pale silver, the amber of old wood.
Xavier stood at his window for a long time after the others had gone to explore their own rooms. Alcmena settled on the sill beside him in cat form, tail curled, watching the canopy with the unhurried attention of something ancient regarding something even older.
"It's different from everything I imagined," Xavier said.
"Did you imagine it?"
"I tried to. On the way here." He pressed his fingertips to the membrane — not glass, something living and slightly warm, yielding the tiniest amount under pressure. "I couldn't. I kept arriving at images that were just human things with the edges changed. Buildings made of wood instead of stone. Forests that looked like parks. I couldn't picture something that was genuinely other."
"And now?"
"Now I think imagination is built from what you've already seen. You can't picture something you have no pieces for." He looked up at the canopy light, the slow pulse of it through the leaves. "This is the first time I've seen pieces I didn't have."
Alcmena was quiet for a moment. When he spoke, his voice had dropped into something quieter than his usual register — not soft exactly, but careful.
"You're going to be fine here, Xavier. I think this place will give you something you've needed for a while. A chance to figure out who you actually are — separate from everything you've been carrying."
Xavier lowered his head slowly. He didn't argue or deflect, which meant the words had landed somewhere real. He was quiet for a moment, then said, "Then I'd like it if you stayed with me through it."
"What a silly thing to say." There was something dry in Alcmena's voice, but underneath it, unmistakably warm. "Of course I will. I always have. I always will."
Xavier looked at him — and the quiet smile that crossed his face was the kind that doesn't perform itself for anyone.

They didn't have long before the door burst open.
"XAVIER!"
Jason didn't wait for an invitation. He strode in with Jupiter behind him, practically vibrating with energy, and stopped in the middle of the room to spread his arms wide as if presenting himself as evidence of something.
"YOOOO — did you see how enormous our rooms are?! Not even my family's house back home could compare, and that's coming from a noble! This is genuinely mind-blowing. I feel like I'm living inside a myth right now!"
Xavier and Jupiter both laughed. Alcmena shifted slightly on the windowsill, settled again, and said nothing — but the faint twitch at the corner of his expression suggested he was listening.
Jason's energy changed without warning — not darkening exactly, but sharpening, pulling both of them closer by the shoulders in the conspiratorial lean of someone who has been holding a question for a while and has run out of patience for it. "So. What's with all this hero business I keep hearing about? Is there something you two have been keeping from me? Because I'm getting the distinct feeling that there is, and I would very much like to be informed."
Xavier and Jupiter looked at each other.
The look lasted about two seconds — enough to confirm they'd both arrived at the same conclusion. And then, sitting down in the warmth of the heartwood room with the triple moons rising outside the window, they told him everything. All of it. The prophecy, the Seven Heroes, what they were actually here for. Everything they'd been holding back until the time was right.
Jason listened. He didn't interrupt once, which was itself remarkable. When they finished, he sat with it for about three seconds — and then exploded.
"WHAT?! SO THAT'S THE ACTUAL REASON WE'RE HERE?! THIS IS THE MOST INCREDIBLE THING I HAVE EVER HEARD IN MY ENTIRE LIFE!"
He immediately spun on them with wide, betrayed eyes. "Why didn't you tell me sooner?! I would have shown up so much more prepared! So much more decked out! You guys have been sitting on this entire fantasy and just — not telling me — do you understand how much I could have bragged about this?! My best friends are the new Chosen Heroes, successors of the legendary Seven, picked by Fate itself — do you understand how incredible that sounds?! I could have told everyone!"
Xavier and Jupiter collapsed into laughter simultaneously — the kind that doubles you over, tears forming — and Xavier managed, barely, between breaths: "That is exactly why we were waiting until we got here to tell you. Mister-cannot-keep-his-mouth-shut."
"Yeah," Jupiter agreed, still laughing.
Jason puffed out his cheeks with the full force of wounded dignity. "You guys are mean. Actual meanies. Both of you."
"We love you too," Xavier said.
From the windowsill, Alcmena watched them — the three of them, loud and laughing in the amber glow of a room inside a living tree in another world entirely — and something in his expression settled into something close to contentment. This was what it looked like when young people found each other. When the bond formed. When the thing that would hold them together through everything to come began to take its real shape.
He watched them a moment longer, then turned his eyes back to the canopy, where the moons hung quiet and brilliant in the dark elven sky.
Today was only the beginning. The heroes didn't know yet what was coming — none of it, or very little of it. But that was as it should be. Some things you could only walk into. You couldn't prepare your way through them.
Their laughter echoed through the heartwood walls of Ilvarael, and the tree, ancient and unhurried and entirely unbothered by the fact that six young humans were currently living inside it, went on breathing around them — as it always had, as it always would — and the night opened wide above them all.
